To all who-m it may concern:

Be it known that I, LEO O. GRANGE, a citizenot the United States,residing at Minneapolis, in the county ot Hennepinand StateotfMinnesota, have invented certain,

new and usetul Improvements in Means tor Removing Solid Tires tromWheels; and I do hereby declare the following to be a tull, i

' tor its object toimprove the same as will v.

hereinafter appear.

As 1s well known, solid ltires are permanently secured to metallic bandsand .are`

mounted on truck or other wheels by pressing the tire band axially ontothe telly bands ot the wheels by means ot a hydraulic press or othermeans. For removing one lot these tires, when worn out, troni a wheel,-said wheel, atter being removed tromy a vehicleis placed on a lower ringot such size'as to directly support the telly band ot the wheel andhaving an external diameter that slightly less than that ot said tellyband. A second ring is placed on top ot the wheel and is ot such size asto directly rest onthe tire band and having an internal diameter` thatis slightly greater than that ot saidv tire band. The lower ring isplaced on the lowered piston ot a hyraulic press, then the wheel isplaced thereon, and the upper ring is placed on said wheel, or in someinstances the lower ring ymay be placed on a truck and wheeled onto thelowered piston atter the wheel and upper ring have been properlypositioned.

The press is then operated to raise the piston and thereby bring theupper ring into Contact with the platen ot the press as a base otresistance. A continued Inovement ot the piston will cause the lowerring to litt the telly band ot the wheel carried thereby while the tireband is held stationary by the upper ring reacting against the platenand press said -telly band out ot the tire band. During the littingmovement ot the telly band, the lower ring enters the tire band andextends completely therethrough at the time the tire band is removedtrom the telly band.

As previously stated, the external diameter ot the lower ring is onlyslightly less than that ot the telly band and hence it the tire band isperfectly true, the same can be easily removed trom the lower ring atterthe upper ring is removed trom the wheel and the wheel trom said lowerring by litting said lower ring out ot the tire band; but many bands otold solid tires are either out ot true or so badly dented by use thatwhen pressed trom a telly band ont'o the lower ring, they engage thesame with such triction that it is necessary to use a Sledgev or othertool to drive the tire band trom the lower ring, which is not only verylaborious but takes considerable time.

By the use ot my invention the lowerl ring may be easily litted trom theremoved tire band.

In the accompanying drawings, which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings:

Fig. l is a fragmentary view principally in central vertical sectionillustrating the invention as used in connection with a hydraulic pressto remove a tire-equipped band trom the telly ot a wheel, some partsbeing illustrated in diiterent positions by means ot broken lines; and

Fig. 2 is a tragmentary viewillustrating a modified torm ot theinventionv and also illustrating vby means ot broken lines a portion ota tireI and its band. i

In the drawings'the're is illustrated a solid Y tire tV permanentlysecured to a metallic band-5 which is secured to the telly band 6 ot atruck wheel 7, ot the artillery type, in

the customary manner by pressing said tire band axially onto the tellyband by the use ot a hydraulic press or other means.

- Referring lirst to the invention as illustrated in Fig. l, thenumerals 8 and 9 indicate, respectively, the platen and piston ot ahydraulic press located, the tormer above the latter, and said piston,when lowered, will be substantiallyv atthe tloor level. Cooperating withthe hydraulic press is a lower ring 10 and an upper ring l1 adapted tobe placed in axial alignment between the platen and piston ot saidhydraulic press,

and the tormer ot said rings is the subjectv matter ot my presentinvention.

The lowerring l0 rests on the "piston 9 and supports the wheel 7 tromwhich the tire 4 is to be removed. This lower ring is of such size as todirectly engage the felly band 6 and the upper ring 11 is of such sizeas to directly rest upon the tire band and be brought into directengagement with the platen 8 when the piston 9 is raised. The lower ring10, as shown, has two external diameters, as indicated at 12 and 13, theformer of which is greatest and is at the upper edge portion thereof, orin other words, at the felly band-engaging portion of said ring, and thewidth thereof is relatively narrow. The smaller diameter 13 of the ringextends to the lower edge thereof and is relatively wide and must have awidth greater than that of the tire band 5. The ring 10 at its greatestexternal diameter 12 is slightly less than that of the external diameterof the felly band 6, and the internal diameter of the ring 11 isslightly greater than that of the tire band 5.

At the time the rings and wheel are assembled on the piston 9 there isconsiderable clearance between the upper ring 11 and the platen 8, butin the drawings, said piston r has been raised sufficiently to bring thering 11 into contact with the platen 8 as a base of resistance to holdthe tire band 6. A further lifting movement of the piston 9 will causethe lower ring 10 to lift the felly band G and thereby move the sameaxially out of the tire band and telescope the same loosely into saidupper ring 11. This lifting movement of the felly band 6 telescopes thelower ring 10 into the tire band 5 and forces the same at its greatestdiameter 12 completely through said tire band so that said tire band isfree to drop onto the piston 9 and loosely surround the ring 10 at itssmallest diameter 13. lt will thus be seen that in case the tire band 5is out of true and tends to stick on the ring 10 at its greatestdiameter 12, the same will be positively forced thereover under theaction of the press.

The piston 9 is then lowered and the upper ring and the wheel removed,and the lower ring 10 lifted from the removed tire band 5.

It is of course understood that the rings 10 and 11 will have to befurnished in different sizes for different sized wheels. In place ofassembling the rings and wheels on the piston of a press, the same maybe assembled on a truck and the truck wheeled onto the piston, which isthe preferred way of handling the same. ln place of making the lowerring with two diameters as shown in F ig. 1, the same may be externallytapered from its felly band-engaging end toward its other end.

Referring now to the invention shown in Fig. 2, there is illustrated aslight modification of the lower ring. In this structure the ring 14 hasa removable upper section 15 for engagement with a tire band, and whichupper section has a greater external diameter than the ring proper. Thisupper ring section 15 is held in place on the ring proper by formingtherewith a plurality of depending circumferentially spaced lugs 16which engage the inner surface of the ring 14.

lVhat l claim is:

1. A ring for use in connection with a hydraulic press or other meansfor removing a tire band from the felly band of a wheel, said ring beingadapted at one of its ends to engage said felly band and having areduced external diameter extending away from its felly band-engagingend and around which reduced portion of the ring said tire band willloosely extend when removed from said felly band.

2. A ring for use in removing a tire band from the felly band of a wheelhaving a removable end section engageable with said felly band, the ringproper being of less external diameter than its removable section toloosely receive therearound the tire band when removed from the fellyband.

In testimony whereof I affix my signa ture.

LEO O. GRANGE.
